Chapter 220: There is a way to heaven

Under the dim table lamp, Song Wenhua put down the information for the day, took off his reading glasses, and rubbed his eyebrows tiredly.
The workload of the recent past is really too great. With his age and energy in his 50s, he gradually felt a little overwhelmed. However, due to the ten years of dying, the 3611 scientific research personnel showed obvious aging problems. Last year he barely recruited a few people. The first graduates after the resumption of the college entrance examination, but they have been working for less than a year, they are still young seeds, and it is still too early to assume the responsibility.
As for the so-called "workers, peasants and soldiers college students" in the early years, they were deformities cultivated in the era when they could be called heroes by handing in a blank paper, not to mention them.
"It's still up to us old guys to hold on for a few more years," Song Wenhua sighed, stood up, moved his sedentary body, walked to the window, looked far away, and Rongcheng was reflected in the afterglow of the setting sun. Quiet and peaceful.
"Ling Ling Ling", the phone rang on the table, interrupting Song Wenhua's thoughts, he returned to the table, picked up the receiver, and a respectful greeting came from the receiver: "Is it Teacher Song? This is Tan Zhenhua."
To be honest, Song Wenhua's perception of his disciple, who he recognized on a whim, has always been very complicated. If you say you like it, you really like it.
There is so much clever energy in this kid, and nothing else, just the "4-rotor drone" he tossed about. Regardless of the rough workmanship, it looks like a toy made by a child. In many places, it is obvious that there is ignorance about the design of the aircraft, but after careful consideration, it has revealed genius ideas.
Others don't know that Song Wenhua is a veteran of the aviation industry, so how can he not know? This kind of multi-rotor structure is an unstable system in a typical aircraft design. It is the most difficult to control. At present, only the Yingchan family on the entire Bluestar has conducted some pre-research work on multi-rotor systems, and has not heard of it. With mature products coming out, the main problem lies in the aircraft's perception of its own state and flight control.
But this little guy uses a "z80" CPU, a simple 4-way power controller and a piece of code to solve this problem. Behind the seemingly simple combination design, it is impossible to do all of this without a solid foundation in electronics. If it is properly cultivated, it must be a good seed for China's aviation industry in the future.
But this guy, who obviously has such a great talent, refuses to work hard in this area, and actually threatened to go abroad in front of him.
If you go abroad, you can go abroad. It is a right way to learn advanced knowledge and return to China to help the construction of the motherland. When New China was founded, a large number of students who had studied abroad returned to China and made great contributions to laying the foundation of China’s scientific research. But the purpose of this kid going abroad is to make more money...
It's really maddening!
Therefore, if he catches the opportunity, he will knock on this kid, so that he should not forget his roots. Well, today the old man is in a bad mood, and this kid slammed into the door so hard that he just used him as a punching bag. Reduce stress by yourself.
So, he snorted angrily: "This is Song Wenhua, I heard that your TOEFL test is good? How is it? Is the school scheduled? You do not practice oral English at home and harass my old man? Your teacher Guo Didn’t you tell you, I’ve been very busy recently, don’t you bother me if it’s okay?
Tan Zhenhua, who was holding the microphone, was suffocated when he heard this, and said to his heart what's wrong. Did this old man take gunshot today? So aggressive? Didn't offend his old man when I asked Ann to report recently? I couldn't understand it for a while, so I had to be more careful and said: "Mr. Song, do you remember that 4-rotor drone? I recently encountered a little trouble organizing production. I would like to ask you for a favor."
Tan Zhenhua didn't mention this drone, but Song Wenhua was even more popular.
Originally, he wanted to experiment with carbon fiber through this little thing. After knowing the source of the carbon fiber, he deliberately greeted Colonel Mahmoud, who has been cooperating with him all year round. Who knows, this guy doesn't know where. I got cramped, and I didn't agree with anything. I refused to say nothing, and there was no room at all.
Song Wenhua felt that he was at a big loss. In order to build this drone, he had spent a long time not talking about it. He even got a lot of carbon fiber in hand. You know, this thing cannot be produced domestically, and foreign countries have imposed a strict embargo on China. This point on hand is the private goods obtained through hard work. It is not an exaggeration to say that the price is higher than that of gold. The rotor is not used much, but if it is used, it is used. It is always distressed, right?
So, he said angrily: "What's the problem, you won't go to your teacher Guo nearby? He is also an expert, or he specializes in dealing with drones. How can he handle your little things?"
Tan Zhenhua replied with a smiling face: "Teacher Song, I want to say that you and Mr. Guo are both first-class in terms of level, but you two have their own strengths. Mr. Guo teaches and educates people. It is even more solid, but after all, his old man is not the first line of engineering application like you, is it?
But my question here happens to be about engineering applications. This is your area of ​​expertise. So after thinking about it, I beg you to come here. Students can’t do anything about it. The Batie urged orders. It's anxious, this is related to a large amount of foreign exchange income of our country, you always reluctantly, help, can you? "
Tan Zhenhua's words clearly praised Guo Rongwei, and secretly put a big top hat on Song Wenhua, which finally made Song Wenhua feel more comfortable.
It’s true to think about it. Although I didn’t get the benefits I wanted, but after all I helped the country earn a lot of foreign exchange, and finally got a little psychologically balanced, so I hummed from my nostrils and said angrily: What you said makes sense. Let’s talk about it. Please tell me in advance. I have been very busy recently. If your matter takes too much time, I can’t help you."
Tan Zhenhua replied:
It’s hard for me and it’s a piece of cake for you. There are two main things. One is the processing of carbon fiber. We have never touched it here. I don’t know how to start. Since you can do it. The rotor that came out last time must have the resources in this respect, so I want to know with you and see if we can help us process these rotors. The second is the core circuit of the flight control that you helped me change last time. One part is the "single-axis piezoelectric gyroscope". I have been inquiring about it for a long time and I don't know where it is produced. I would like to consult with you on where this thing can be made in China."
When Tan Zhenhua said this, Song Wenhua immediately reacted. When he helped this kid redo the drone, after listening to Tan Zhenhua’s speech, he was itch for a while and changed a lot of good things to the gadget, the most important of which was These are the two.
Carbon fiber is currently regarded as a rare item in China, and it is normal that it has not been seen in the civilian market. Only the top scientific research unit of the aerospace system such as the 3611 where he works has a little small-scale processing capability.
As for the "single-axis piezoelectric gyroscope", it is even more rare. To discuss the source, it is a derivative product of pre-research by China in the 1970s to solve the problem of miniaturization of missile seekers. Although the one installed on the drone is not What kind of high-quality goods, the accuracy is also poor, but how can ordinary people have this channel to buy? It's no wonder Tan Zhenhua is coming to beg for himself.
This is really, there is a way to heaven, you don’t go, and there is no way to hell, you just break in!
